I snapped this quick image out of an upper story internal window at the Louvre and upon review it really appealed to me; something about the placement or spacing of statues, people and foliage? Or the architecture? or lines? ????

Can someone explain? Or is it just appealing to me?

There is a fair amount of distortion in this photo. Do you notice it, especially on the left side?

I presume you're judging by the shadow lines? The roof is a semi cylinder (not sure what the architectural name is) and I think distortion would have affected the pillars in the top left and the woman in the middle left, which I do not see. Also, if you look at the original size, you'll see the connecting lines between the stone/marble floor - they're straight. Distortion would impact everything, not just the roof shadow.

I see. But the pic still doesn't look right for some reason. But nice try.
